某型夹心取力器输入轴断裂原因分析及解决措施
|
摘要
某型夹心取力器装置输入轴根部断裂,花键轴近输入端有明显变形、裂纹,通过计算分析主要原因为输入轴承受载荷过大。改型离合装置在保留扭转减震功能的前提下,增加了夹心取力器输入轴过载保护功能,可以有效防止夹心取力器输入轴承受过大载荷,满足使用需求。
The root of the input shaft of a type of sandwich power take-off device is broken, and the near input end of the spline shaft has obvious deformation and crack. Through calculation and analysis, the main reason is determined as the input bearing is overloaded. Under the premise of retaining the torsional vibration reduction function, the modified clutch device increases the overload protection function of the input shaft of the sandwich power take-off, which can effectively prevent the input force of the sandwich power take-off bearing from being overloaded and meet the needs of use.
